Since phosphate groups have a negative charge, adding them to histone tails neutralizes them and probably reduces their affinity for DNA. It might contribute to transcription because it stimulates histone acetyltransferases which cause histone acetylation and enhance transcription.

What type of molecule is a histone?
Protein Molecules. "Dna coild around protein molecules called histones."
What is the role of proteins in allowing DNA to fit in a cell?
The protein histone, and attendant proteins, spool the DNA tightly around their complexes and then further wind these complexes into tighter and tighter shapes. About two meters worth of DNA per cell is held in these histone complexes.
How many different types of histone subunits are present in a nucleosome?
the number of histone subunits in a nucleosome is?
What is reverse phosphorylation?
Reverse phosphorylation is a process that involves the removal of phosphate groups from proteins or molecules, in contrast to the more common process of adding phosphate groups (phosphorylation). This dephosphorylation often plays a regulatory role in various cellular processes, signaling pathways, and protein functions.
When do histone deacetylase discovered?
Histone deacetylases (HDACs) were first discovered in the late 1990s. The identification of these enzymes was pivotal in understanding the regulation of gene expression through the modification of histone proteins. HDACs play a crucial role in the removal of acetyl groups from histones, leading to a more compact chromatin structure and reduced gene transcription. Their discovery has since led to significant research into their roles in various cellular processes and diseases.
What is histone mRNA?
Histone mRNA is a type of messenger RNA (mRNA) that carries the genetic information for the synthesis of histone proteins. Unlike typical mRNAs, histone mRNAs lack a poly-A tail and are rapidly degraded after histone protein synthesis is complete. They play a crucial role in packaging DNA into chromatin structure.
What are the key findings and insights from the latest histone modifications review?
The latest review on histone modifications highlights key findings such as the role of histone modifications in gene regulation, chromatin structure, and cellular processes. Insights include the impact of histone modifications on disease development and potential therapeutic targets.
What is the role of water in cyclic photo phosphorylation?
It provides electrons and protons.

What is the major function of a histone protein?
Histone proteins act as spools around which DNA is wound, helping to package and condense the DNA into chromatin. They also play a role in regulating gene expression by controlling access to DNA for transcription factors and other proteins.
What are nonhistones?
histone are nonprotienous
Does ATP contain histone?
No, it does not.
